Install celestia-node ​

Installing from source ​

This section goes over building and installing celestia-node. This tutorial assumes you completed the steps in setting up your development environment.

Install the celestia-node binary by running the following commands:

  1. Remove any existing copy of celestia-node, clone the repository, and change into the directory:

    bash
    cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
    cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/

  2. Check out to the desired version, based on the network you will use:

    bash
    git checkout tags/v0.16.0
    git checkout tags/v0.16.0
    bash
    git checkout tags/v0.16.0
    git checkout tags/v0.16.0
    bash
    git checkout tags/v0.18.1-arabica
    git checkout tags/v0.18.1-arabica

  3. Build the celestia binary:

    a. Standard build

    bash
    make build
    make build

    b. Experimental build

    OPTIONAL

    If you're a node operator comfortable with experimental features and seeking optimal performance with minimal RAM usage, this option is recommended for you.

    bash
    make build-jemalloc
    make build-jemalloc

    This build option enables CGO, and downloads and installs jemalloc. Learn more about the build command.

  4. Install the binary:

    bash
    make install
    make install

  5. Build the cel-key utility:

    bash
    make cel-key
    make cel-key

  6. Verify that the binary is working and check the version:

    bash
    celestia version
    celestia version

The output will show the semantic version of celestia-node, commit hash, build date, system version, and Golang version.

Installing a pre-built binary ​

Installing a pre-built binary is the fastest way to get started with your Celestia data availability node. Releases after celestia-node v0.13.3 should have these binaries available.

The steps below will download a binary file named celestia. Depending on the setup that you choose during installation, the celestia binary will be available at either:

  • $HOME/celestia-node-temp/celestia
  • /usr/local/bin/celestia

Pre-built binaries are available for:

  • Operating systems: Darwin (Apple), Linux
  • Architectures: x86_64 (amd64), arm64

To install the latest pre-built binary you can run this command in your terminal:

bash
bash -c "$(curl -sL https://docs.celestia.org/celestia-node.sh)"
bash -c "$(curl -sL https://docs.celestia.org/celestia-node.sh)"

Follow the instructions in the terminal output to choose your installation preferences.

You will see an output with the menu for celestia.

Next steps ​

First, we recommend reading the overview of our node types, if you haven't yet.

Now that you've installed Celestia Node, it's time to pick your node type and run your node!

If you're planning to run a light node, we recommend the node RPC CLI tutorial.

Upgrading your binary ​

To upgrade your binary, you can install the latest version from the instructions above and restart your node. If you run into any issues, Refer to the troubleshooting section.
